Best Practice Guide for Office Buildings

OFFICE BUILDINGS Office Building Lighting Control Design Guidelines A well designed control system requires the consideration of energy codes, the occupants’ and building owner’s control needs, building use patterns and the type of lighting that is used in each space. Listed below are some general lighting control principles for individual spaces, multi-occupant spaces, exterior lighting, and whole buildings. General • Where daylighting is available, provide daylighting controls. Use continuous dimming for spaces with minor motion and high concentration activities such as reading, writing, and conferencing. Use stepped dimming (on/off switching) for spaces with major motion activity such as walking and shelf stocking. • To prevent false triggering, always mount ultrasonic occupancy sensors at least 6 to 8 ft. away from HVAC ducts on vibration free surfaces and position them so there is no detection out the door or opening of the space. • In spaces where there is a strong sense of occupant ownership, such as private offices, always include switches for local off control of the lighting. Use manual-on control for added energy savings. If concerns exist that lighting could be turned off, automatically or manually, when spaces are still occupied, put in emergency lighting for safe egress. • Many lighting control devices have specific voltage and load ratings requirements. Be sure to specify the device model that matches the correct voltage and load rating for the application. • Conference Rooms • Use dual technology occupancy sensors in larger conference rooms for optimal detection of both small hand motion and larger body movement. • Use ceiling or corner-mounted passive infrared occupancy sensors for medium and small conference rooms. • Always include switches for manual-on operation or to provide manual override control of the lighting. Cubicles • Control plug loads such as task lighting, computer monitors, portable fans and heaters with an occupancy sensor controlled plug strip. • Mount personal occupancy sensor beneath binder bin or desk and position it to avoid detecting motion outside cubicle area. Hallways/Elevator Lobbies/Common Areas • Use time scheduling or occupancy sensors for automatic on/off control of lighting. Kitchens/Lunch Rooms • Ceiling- or corner-mounted passive infrared occupancy sensors are typically used. Private Offices • Use ceiling-mounted, corner-mounted or wall switch passive infrared occupancy sensors for medium and small offices, dual technology sensors for larger offices. • Always include switches for manual-on operation or to provide manual override control of the lighting. 6 Watt Stopper/Legrand
